To clarify 3 nodes 2 wired (including main of course) 1 wireless The non-main wired node ignores the fact it is wired and talks over wi-fi to main, halving the effective speed.

Check this document for suggestions how to properly wire Deco mesh units: General questions about Ethernet Backhaul feature on your Deco

Does not help. After searching over and over for information about which backhaul routers/switches support deco, it is very conflicted. One post says a particular switch does work with deco, the next says the same switch doesn't. Even many TP-Link switches have articles about how they don't work with Deco. How are you supposed to know which to buy? And why do we need backhaul at all - this is just customer unfriendly. This could have been handled in software to let nodes talk directly to the internet when on ethernet and then share information with each other over wifi.
